operating security screening checkpoints. Garrett's experience ranges from very small—
one and two detector checkpoints—to very large, 900-detector Olympic operations. Garrett
always prefers to work closely with its clients when designing checkpoints. Every client has
a unique situation and needs a somewhat customized solution. Garrett is happy to assist in
designing and implementing these solutions. This section is intended to provide general in
formation for designing security screening checkpoints.
2.1.1 eLeCTrICAL POWer
Electricity is a critical element for successful, trouble-free installations. Garrett metal detectors
require 100-240 Volt, 50/60 Hertz power, and draw less than 2 amperes each. Consequently,
"power load" is minimal for any group of detectors.
Due to their pulse induction technology, it is required that all PD 6500i units
within 25' to 100' of each other be connected to the same phase of the AC power source;
otherwise, a Master / Slave configuration must be used. (See Section 2.3.)
Connecting to a single power source can be easily accomplished using extension power cords
connected to the same outlet if existing power does not, or cannot, meet this requirement. An
optional 10' power cord jumper is available to simplify this connection. (See Section 8.2.)
Garrett metal detectors are very versatile and can be connected to power from either
the top or bottom of either side. This makes connecting power very convenient and gives
users more options when designing their sites. When "running" power along the ground it is
recommended that cords be secured to the ground using highly visible industrial tape or cable
trays. This ensures that the cord is visible to patron traffic and prevents personal injury as well
as equipment damage. When "running" power overhead it is recommended that power cords
be suspended above the detector. This keeps the cord accessible for maintenance, but out of
reach of regular traffic.
2.1.2 PHYsICAL sITe
Appropriate selection and preparation of a site is paramount for successful, efficient and
effective checkpoint screening operations. The site must be flat, level and free from obstruc-
tions. The surface must be solid and free from any vibration or movement. Most indoor
surfaces are already adequate. Outdoor surfaces should be asphalt or concrete; wooden or
metal platforms can NOT be used. The site should be free from running or standing water and
should provide protection from weather elements. An industrial, four-walled tent is the best
way to provide shelter from the weather elements when outdoors. The tent must be strong
enough to repel rain, snow, sleet and a fair amount of wind.
2.1.3 CHeCKPOINT CONFIGUrATION
A site must also allow for efficient spacing and configuration of metal detectors. If a
site is too small the operation of the checkpoint becomes "choked" and "bottlenecks"
form. This severely hampers the flow of "traffic" through a checkpoint and can be troublesome
when trying to operate within time constraints. If a site is too big it becomes difficult to oversee
the checkpoint, and valuable space is wasted. As a general rule a rectangular block of space,
